AK: of course, you the player dont learn that until the game ends its second act, and Angel begs you to kill her, end her suffering, foil her father’s plans
AK: see, you are one of six VAULT HUNTERS, soldiers of fortune that pursue vaults in hope of wealth and glory
AK: Handsome Jack tricked you, first into a death trap that should have been a job interview, then into almost destroying the resistance you stumbled into championing
AK: it is chance and revenge that brought the vault hunters this far, and boredom that commanded you
AK: but it will be the moral outrage of her death that makes you see this through
AK: for her sacrifice has no practical outcome
AK: Jack opens the vault regardless, is killed thereafter
AK: to the end he thought he was a hero
AK: that you had murdered his daughter only made it that much more obvious to him
AK: that he would have killed millions on this planet alone had already killed thousands to stand before that altar, made it a difficult hypothesis for you to accept
